This pre-mixed pigment is a semi-transparent blue gray. Highly
lightfast and mildly staining, Payne's Gray is a cool dream in a wet
sky.

Use this pigment instead of Indigo, except where yellow is involved.
Payne's Gray helps create flat ocean waters and "after the storm" clouds
and skies. Rocks and granite boulders, including their shadows, can be
quickly rendered with light dilute washes or more concentrated
brushloads.
